Abstract

"PROCESSO PARA PREPARAçãO DE éTERES BENZìLICOS" O assunto da invenção é o processo para preparação de éteres mistos da fórmula geral (I) onde Ar representa uma porção alicíclica, aromática ou uma ou mais porções heterocíclicas contendo heteroátomo, opcionalmente substituída por um ou mais alcóxi C~ 1-4~, metilenodióxi, alquila C~ 1-4~, halogênio, haloalquila C~ 1-4~ ou grupo nitro, e/ou condensado com um anel benzeno, R^ 1^ e R^ 2^ independentemente representam grupo hidrogênio, alquila C~ 1-4~, haloalquila C~ 1-4~, alquenila C~ 2-4~, fenila, fenila substituída, grupo cicloalquila C~ 3-6~, R^ 3^ significa grupo alquila C~ 1-6~, alquenila C~ 3-6~ ou aquinila C~ 3-6~, opcionalmente substituído por um ou mais grupos alquila C~ 1-6~, alquenila C~ 3-6~, alquinila, C~ 3-6~, haloalquila C~ 1-6~ou átomo de halogênio; ou um grupo alquilóxi C~ 1-4~-alquilóxi C~ 1-4~-alquila C~ 1-4~, <B>CARACTERIZADO<D> pelo fato dos compostos da fórmula geral II, onde X significa hidróxi, halogênio ou grupo de partida sulfoéster, serem reagidos, em presença de ácido, ácido de Lewis, óxido metálico ou carbonato metálico com 1-3 equivalentes molares do álcool da fórmula geral III, R~ 3~-OH onde o significado do substituto é conforme definido acima, o éter resultante da fórmula geral I é isolado, caso desejado, estabilizado por adição de uma base e/ou um antioxidante, e, caso desejado, o excesso do álcool é recuperado.
